Step-by-step explanation:
Hi there!
Slope-intercept form: 
where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x is 0)
<u>1) Plug in the slope (</u><u><em>m</em></u><u>)</u>
We're given that the slope is 
. In , replace <em>m</em> with :
<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>
We're given the point (-9,4). Plug this point into the equation as 
and solve for <em>b</em>:
Subtract 
from both sides to isolate <em>b</em>:
Therefore, the y-intercept is . Plug this back into as <em>b</em>:
I hope this helps!
Answer:
y = mx + b
m = slope
b = y-intercept

Answer:
300 burgers
Step-by-step explanation:
You can set up an equation like this: 50+0.05x=20+0.15x
Then, subtract 0.05x from both sides: 50=20+0.10x
Subtract 20 from both sides: 30=0.10x
Divide by .10 on both sides: 300=x
X represents how many burgers must be sold for the boys to have earned the same amount of money, and that is 300 burgers.
